Alright - maybe let's do static pressure test, and leakdown time.

Plug in FP guage, turn on key to prime rails. If it's not @ 43+ PSI, turn the key off and on again.

If you don't get it then, GENTLY pinch the fuel return line, and prime the rails again (this will NOT yet rule out the FPR), but will tell a line leak, or leaking injector, or (not likely), a bad pump check valve.

Post back on that...

And cold starts and running like bats from Hades means NOTHING. (and do bats actually 'run'??? maybe they do, to V1, then roll flaps and go for V2?)
